Integrated Upper Ordovician Graptolite–Chitinozoan Biostratigraphy of the Cardigan and Whitland Areas, Southwest Wales
Geol. Mag. 145 (2), 2008, pp. 199–214. c 2007 Cambridge University Press 199 doi:10.1017/S0016756807004232 First published online 17 December 2007 Printed in the United Kingdom Integrated Upper Ordovician graptolite–chitinozoan biostratigraphy of the Cardigan and Whitland areas, southwest Wales THIJS R.

In the Cardigan district, finds of Armoricochitina reticulifera within strata referred to the clingani graptolite Biozone (morrisi Subzone), together with accessory species, indicate the Fungochitina spinifera chitinozoan Biozone, known from several Ordovician sections in northern England that span the base of the Ashgill Series. Tanuchitina ?bergstroemi, eponymous of the succeeding chitinozoan biozone, has tentatively been recovered from strata of Pleurograptus linearis graptolite Biozone age in the Cardigan area. The T. ?bergstroemi Biozone can also be correlated with the type Ashgill Series of northern England. Chitinozoans suggest that the widespread Welsh Basin anoxic–oxic transition at the base of the Nantmel Mudstones Formation in Wales, traditionally equated with the Caradoc–Ashgill boundary, is of Cautleyan (or younger Ashgill) age in the Cardigan area. -
Researching Stonehenge: Theories Past and Present
Parker Pearson, M 2013 Researching Stonehenge: Theories Past and Present. Archaeology International, No. 16 (2012-2013): 72-83, DOI: http://dx.doi.org/10.5334/ai.1601 ARTICLE Researching Stonehenge: Theories Past and Present Mike Parker Pearson* Over the years archaeologists connected with the Institute of Archaeology and UCL have made substantial contributions to the study of Stonehenge, the most enigmatic of all the prehistoric stone circles in Britain. Two of the early researchers were Petrie and Childe. More recently, colleagues in UCL’s Anthropology department – Barbara Bender and Chris Tilley – have also studied and written about the monument in its landscape. Mike Parker Pearson, who joined the Institute in 2012, has been leading a 10-year-long research programme on Stonehenge and, in this paper, he outlines the history and cur- rent state of research. Petrie and Childe on Stonehenge William Flinders Petrie (Fig. 1) worked on Stonehenge between 1874 and 1880, publishing the first accurate plan of the famous stones as a young man yet to start his career in Egypt. His numbering system of the monument’s many sarsens and blue- stones is still used to this day, and his slim book, Stonehenge: Plans, Descriptions, and Theories, sets out theories and observations that were innovative and insightful. Denied the opportunity of excavating Stonehenge, Petrie had relatively little to go on in terms of excavated evidence – the previous dig- gings had yielded few prehistoric finds other than antler picks – but he suggested that four theories could be considered indi- vidually or in combination for explaining Stonehenge’s purpose: sepulchral, religious, astronomical and monumental. -

Archaeological and Geochemical Investigation of Flint Sources In
Archaeological and geochemical investigation of flint sources in Britain and Ireland By Seosaimhín Áine Bradley A thesis submitted in partial fulfilment for the requirements of the degree of Doctor of Philosophy at the University of Central Lancashire MARCH 2017 1 ABSTRACT This study investigates the archaeological use of flint in Britain and Ireland from the Mesolithic to the Bronze Age through geochemical analysis of flint samples obtained from the major areas of chalk geology within these islands (Northern, Southern, Transitional, and Northern Ireland), and provenancing of artefactual assemblages. Recent approaches to provenancing flint have demonstrated that this is indeed possible, however this approach encompasses a larger study area and provides a comparison of two methodologies, one destructive (acid digestion ICP-MS) and one non-destructive (pXRF). Acid digestion ICP-MS and pXRF are capable of detecting a range of elements in a given sample, although they each have specific advantages and disadvantages when applied to archaeological material. There are three main research questions that are addressed in this thesis: ● Determine geochemical composition of flint samples from primary chalk outcrops; ● Assess differences between flint from different chalk provinces; ● Compare acid digestion ICP-MS and pXRF in achieving these objectives. The results indicate that flint from the major areas of chalk geology in Britain and Ireland can be distinguished using the methodologies stated above. There are some difficulties in distinguishing between the Southern and Northern Ireland chalk province flint samples, however the samples from the Northern chalk province are very well differentiated. Archaeological assemblages chosen from throughout the study area and from a wide chronological span were sampled using pXRF and subjected to statistical analysis. -
Stonehenge 'Bluestone' Quarries Confirmed 140 Miles Away in Wales 7 December 2015
Stonehenge 'bluestone' quarries confirmed 140 miles away in Wales 7 December 2015 somewhere in the Preseli Hills, but only now has there been collaboration with archaeologists to locate and excavate the actual quarries from which they came. Director of the project, Professor Mike Parker Pearson (UCL Institute of Archaeology), said: "This has been a wonderful opportunity for geologists and archaeologists to work together. The geologists have been able to lead us to the actual outcrops where Stonehenge's stones were extracted." The Stonehenge bluestones are of volcanic and igneous rocks, the most common of which are called dolerite and rhyolite. Dr Richard Bevins (Amgueddfa Cymru – National Museum Wales) and Dr Rob Ixer (UCL and University of Leicester) have identified the outcrop of Carn Goedog as the main source of Stonehenge's 'spotted dolerite' Excavation of two quarries in Wales by a UCL-led bluestones and the outcrop of Craig Rhos-y-felin as team of archaeologists and geologists has a source for one of the 'rhyolite' bluestones. The confirmed they are sources of Stonehenge's research published today details excavations at 'bluestones'– and shed light on how they were Craig Rhos-y-felin specifically. quarried and transported. The special formation of the rock, which forms New research by the team published today in natural pillars at these outcrops, allowed the Antiquity presents detailed evidence of prehistoric prehistoric quarry-workers to detach each megalith quarrying in the Preseli hills in Pembrokeshire, (standing stone) with a minimum of effort.

The project was funded by the Welsh Government’s Sustainable Development Fund. This is a pilot project so we would love to receive your feedback on this information pack. You can send your comments to [email protected] or leave your comments in the visitor book. Pembrokeshire Coast National Park Welcome to Pembrokeshire Coast National Park! Pembrokeshire lies at the south west extreme of Wales and is surrounded on three sides by the sea. Pembrokeshire's marine and terrestrial environments are strongly influenced by the Gulf Stream and the National Park supports species found in both warmer, southern areas as well as those from colder, northern regions. Pembrokeshire is internationally important for many of its coastal, marine and lowland heath habitat as well as ancient, semi-natural oak woodland in the North of the park. These habitats support some of our most iconic species including choughs, puffins and seals. The high wildlife value of the Park is reflected by its nature conservation designations which include: 13 Special Areas of Conservation (3 Marine SACs overlap about 75% of the Park coastline and account for about 60% of the inshore area). 5 Special Protection Areas. 1 Marine Nature Reserve (Skomer) – one of three in the UK. 7 National Nature Reserves. 60 Sites of Special Scientific Interest. With miles of rugged coastline, sandy beaches, farmland, valleys, hills and woodlands to explore, we hope this short guide will help you experience some of the fabulous wildlife our National Park has to offer. -

Architecture and Meaning in the Structure of Stonehenge, Wiltshire, UK Timothy Darvill
Houses of the Holy: architecture and meaning in the structure of Stonehenge, Wiltshire, UK Timothy Darvill Timothy Darvill is Professor of Archaeology in the Department of Archaeology, Anthropology and Forensic Science, Bournemouth University, UK. His research interests lie in the Neolithic of Northwest Europe and in archaeological resource management, and he has carried out fieldwork in Germany, Russia, Malta, England, Wales, and the Isle of Man. In 2008, together with Geoff Wainwright, he undertook excavations inside the stone circles at Stonehenge as part of ongoing research into the links between Stonehenge and the sources of the Bluestones in the Preseli Hills of southwest Wales. He is a member of the Editorial Advisory Board of Time & Mind. [email protected]. Abstract Stonehenge in central southern England is internationally known. Recent re-evaluations of its date and construction sequence provides an opportunity to review the meaning and purpose of key structural components. Here it is argued that the central stone structures did not have a single purpose but rather embody a series of symbolic representations. During the early third millennium this included a square-in- circle motif representing a sacred house or ‘big house’ edged by the five Sarsen Trilithons. During the late third millennium BC, as house styles changed, some of the stones were re-arranged to form a central oval setting that perpetuated the idea of the a sacred dwelling. The Sarsen Circle may have embodied a time- reckoning system based on the lunar month. From about 2500 BC more than 80 bluestones were brought to the site from sources in the Preseli Hills of west Wales about 220km distant.
